[bug] pouch inspect -f {{.ExecIDs}} returned error

[zjumoon01]

Ⅰ. Issue Description

pouch inspect -f {{.ExecIDs}} is not supported.

#pouch inspect -f {{.ExecIDs}} test-lifecycle-exec-01251548410259
Error: Template parsing error: template: :1:2: executing "" at <.ExecIDs>: can't evaluate field ExecIDs in type *main.inspectContainerJSON

Ⅱ. Describe what happened

It returned error.

Ⅲ. Describe what you expected to happen

It should return its ExecIDs.

Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. start a container
2. pouch exec into the container
3. start a new terminal, and pouch inspect -f {{.ExecIDs}}

Ⅴ. Anything else we need to know?

In fact, {{.ExecIds}} is supported. But "ExecIds" is a variable in code , not json string.
Pouch should support ExecIDs, not ExecIds

Ⅵ. Environment:

• pouch version (use pouch version): 1.2.0
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a): 4.9
• Install tools:
• Others:

You should use pouch inspect -f {{.ExecIds}}. But we truly not support inspect execids now, I will create PR to fix it.

@zjumoon01 could you share your usage here? the execID seems useless thing I guess. Thanks

It is an ops method. Sometimes "exec" is not exited correctly because some bug on docker environment. So inspecting ExecIDs is useful to debug. It will be useful in pouch debug.
